San Francisco police are looking for a man who hit a woman with a bottle in the Castro Wednesday night, August 27.

The incident occurred at 7 p.m. at 18th and Castro streets when the suspect, a white male in his 30s, approached the woman, 63, “and started a verbal argument,” Officer Gordon Shyy, a spokesman for the San Francisco Police Department, said in a summary.
